Former Sen. John Breaux (D-La.) is leaving Patton Boggs to form his own firm with his lobbyist son, John Breaux Jr.   

Breaux has worked at the lobbying firm since retiring from the Senate in 2004. He said in a statement that he may continue to have an association with the firm, which was co-founded by fellow Louisianan Thomas Boggs.

“Tom Boggs and the Patton Boggs firm have been a professional family for me since I retired from the Congress almost three years ago. It has been a rewarding experience in which I have learned a great deal from my colleagues, who are also my friends, but the challenge and opportunity to start a new business with my son is something that I cannot pass up,” Breaux said in a statement sent to Patton Boggs employees.

Breaux and Patton Boggs were continuing to discuss how Breaux could continue to serve as counsel and provide strategic advice to the firm, according to the statement.

Breaux’s announcement comes two days after the surprise retirement of Sen. Trent Lott (R-Miss.), who is expected to begin a lobbying career. Some lobbyists have speculated that Lott and Breaux, both known as dealmakers in the Senate, might go into business together. Lott’s son Chester is also a lobbyist.

Chester Lott told Bloomberg News that his father was considering lobbying with Sen. Breaux, and said the two have a “great relationship.”

Thomas Boggs praised Breaux in a statement announcing the former senator’s departure: “We have all benefited immeasurably from our personal and professional association with John, we wish him well in his new venture, and look forward to continuing our personal friendship and professional collaboration for many years to come.”
